My Galaxy S5 sometimes doesn’t recognize my fingerprint

A: For best results, swipe the entire pad of your finger, from base to tip, across the home key to register your fingerprint properly. If you bend your finger or use a fingertip, the device may not recognize your fingerprints.
Besides, if you use the accessory like key protector on your device, the device may not also recognize your fingerprints. Keep your finger flat against the home key and swipe at a moderate speed. The fingerprint sensor is sensitive to moisture, so make sure both the screen and your fingertip are dry. The Home button contains the fingerprint recognition sensor. To ensure that the Home button is not scratched or damaged, please avoid contact with metal objects, such as coins, keys, and necklaces.
